DWORD GetAspectRatioFilter(hdc) | |||||
HDC hdc; | /* handle of device context | */ |
The GetAspectRatioFilter function retrieves the setting for the current aspect-ratio filter. The aspect ratio is the ratio formed by a device's pixel width and height. Information about a device's aspect ratio is used in the creation, selection, and display of fonts. Windows provides a special filter, the aspect-ratio filter, to select fonts designed for a particular aspect ratio from all of the available fonts. The filter uses the aspect ratio specified by the SetMapperFlags function.
hdc
Identifies the device context that contains the specified aspect ratio.
The low-order word of the return value contains the x-coordinate of the aspect ratio if the function is successful; the high-order word contains the y-coordinate.
